METALLIC DOOR.

SPECIFICATION forming part of Letters Patent No. 433,376, dated July 29,1890.

Application filed July 12, 1889.

To all whom it may concern:

Be it known that 1, WILLIAM R. STIRLING, of Chicago, Cook county,Illinois, have in .vented a new and useful Improvement in MetallicDoors, of which the following is a full, true, and exact description,reference being had to the accompanying drawings.

This invention relates to an improved sliding door, and is especiallyadapted to that class of doors used to close freight-ears, but

may be used for other purposes; and it consists of a combination of suchdoor with supportin and closing devices, whereby the same is readilyopened and closed, and when closed I5 is tight against the ingress ofmoisture.

My door itself consists of a box-shaped structure of pressed steelhaving inwardlyprojecting flanges at the sides, and preferably at thetop, formed integral with the door itself,

while the body of the door is preferably made of corrugated material.

The method of sustaining this door will be readily understood from theaccompanying drawings, in which- Figure 1 represents an elevation, andFig. 2a horizontal cross-section.

A represents the door, preferably boxshaped in structure, and preferablycorrugated, as indicated. The said door has inwardly-projecting flangesF G at the sides,

which flanges are by preference carried around the top and bottom, asindicated at L. The

door itself is carried upon the rail II by means of rollersJ J. At oneside of the opening of the door is the flange E, against which theflange F engages when the door is closed. At the opposite side is theflange or projection D, against which the flange G engages Serial No.317.284. (No model.)

when the door is closed, and the flange F may engage when the door isopen. The flange D must not project beyond the inner surface of thecorrugations. These flanges or strips 1) E may be supported inanysuitable way as, for instance, upon the posts B G. WVhen the door isclosed, both flanges D E engage with the flanges F G of the door, whilewhen the door is open the flange D arrests the further motion of thepart F of the door.

That I claim as my invention, and des re to secure by Letters Patent,is-

1. The pressed-steel door having corrugations in the body thereof, andinwardly-projecting flanges on two sides, all made of one piece ofmetal, substantially as described.

2. The corrugated door A, having a flange extending around the same andmade of pressed steel and of one piece of metal, sub stantially asdescribed.

3. The combination of the corrugated door A, the i11ternally-projectingflanges E G, integral with the door, and the stationary strip D,engaging with the flanges F G, substantially as described.

4.. The combination of the corrugated door A, the internally-projectingflanges F G, integral with the door, and the stationary strips D E,engaging with the flanges F G, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. I

WILLIAM R. STIRLING.
